Eral, the results showed that temperature is an importantimportant parameter to control the efficiency of ibuprofen removal. perature is definitely an parameter to handle the efficiency of ibuprofen removal. three.five. Photocatalytic Degradation of Ibuprofen Optimization of adsorption condition only accomplished 22 of ibuprofen removal on -Fe2 O3 . The low surface area and non-porosity of iron oxide may perhaps restrict the number of accessible Thromboxane B2 custom synthesis internet sites for ibuprofen adsorption. Since iron oxide features a band gap of energy at 2.three eV which can utilize photon power up to 600 nm [51], its activity as a photocatalyst was evaluated for degradation of ibuprofen. Figure 12 shows the effect of UV-light irradiation onMaterials 2021, 14,Figure ten. Impact of initial concentration of ibuprofen (Co) in the course of adsorption making use of Fe2O3-G-500.13 ofFigure 11 illustrates the effect of temperature on the adsorption capacity of ibuprofen even though working with Fe2O3-G-500 as adsorbent. The adsorbed capacity was decreased from 55 mg/g the removal of ibuprofen using -Fe2 O3 -G500. Three sets of experiments were conducted; in dark to represent adsorption, at 45 within 60irradiation, and lightadsorption capacat area temperature to 22 mg/g quick light min. The decrease in irradiation immediately after 20 minhigh temperature implied the reduction of photocatalytic degradation of ibuprofen ity at of adsorption (Figure 1). It is actually apparent that physical interaction involving ibuprofen usingthe iron 3 -G500 elevated High temperature also up to 53 . When comparedof ibuand -Fe2 O oxide active internet site. the removal efficiency enhanced the diffusion price with MCC950 NOD-like Receptor removalfrom the surface of adsorbent and enhanced repulsion of ibuprofen adsorbed ibuprofen without UV light (dark adsorption only), the removal between the only reached 28 . Even so, the combination ofbarrier [480]. In general, the results showed that temprofen molecules producing a steric adsorption followed by UV irradiation increased the ibuprofenis an important80 . perature removal up to parameter to handle the efficiency of ibuprofen removal.Components 2021, 14, x FOR PEER REVIEWFigure 11.

Conclusions Iron oxide (Fe2O3-G) with uniform hexagonal flake morphology has been effectively synthesized applying a combination of gelatin as a all-natural template and F127 as a syntheticMaterials 2021, 14,14 ofThe activity of iron oxide as photocatalyst substantially enhanced the removal of ibuprofen by means of photodegradation. Preliminary adsorption prior to irradiation has optimized the interaction between ibuprofen.
